The invention relates to applications of a beta-glucan extract product in the immunological enhancement of poultry animals, and specifically provides a kit. The kit includes as follows: (1) an immune-enhancer used for enhancing the immunity of poultry animals and includes a beta-glucan extract product extracted from saccharomyces cerevisiae cell walls; and (2) a virus vaccine. Applications of thebeta-glucan extract product extracted from the saccharomyces cerevisiae cell walls in the preparation of the kit and immune-enhancer for enhancing the immunity of the poultry animals are also provided. Immunological enhancement can be performed on the poultry animals by using the beta-glucan extracted from the saccharomyces cerevisiae cell walls, so that lymphocyte proliferative response and T cell response of the poultry animals inoculated with the vaccine can be enhanced; viral load can be reduced; pathogenic rates or mortality can be lowered; antibodies can be generated in advance; antibodyproduction can be enhanced; and / or the diffusion of viruses can be restricted.

The invention discloses an anti-AIDS virus bullatacin patch for external use, which comprises a backing layer, a drug reservoir and an anti-sticking layer; a cotton medicinal non-woven fabrics with good permeability is used as the backing layer, a polymeric gel (an acrylate pressure-sensitive gel) as an adhesive; the patch comprises the prepared liquid of bullatacin, and a silicone-oil anti-sticking polyester film is functioned as an anti-sticking layer. The patch for external use has the advantages that not only the disadvantage of serious harmful and side effects of the existing oral or intravenous antitumor drug are solved, but also the disadvantage of heavy skin irritation and a certain extend of toxicity of traditional patches for external use are overcome, and the economic cost is reduced.

The invention discloses a drug delivery system for external use containing the effective composition of bullatacin locality drug; the effective composition containing the bullatacin locality drug is dissolved in a mixed liquid of absolute alcohol and propylene glycol and fully stirred and mixed, and then prepared into the drug delivery system for external use; the drug delivery system comprises apatch, an aerosol or a film agent. Adoptions of the natural substance bullatacin extracted from cherimoya and an external using manner of the invention overcomes the shortcoming that the antitumor drugs and anti-AIDS drug have to be orally used or intravenously medicated, and the drug delivery system can ensure the drug to be absorbed through the skin, thus slowly releasing the drug and reducing the delivery dosage of the drug and the economic cost for the treatment.

The present invention provides a compound of general formula I: and pharmaceutically acceptable salts and esters thereof. The provided compounds, compositions and methods are useful in the treatment of viral infections, particularly hepatitis C infections.

The invention relates to a plant composition for the treatment or prevention of viral blood-borne diseases such as the diseases caused by the human immunodeficiency virus (HIV) or hepatitis C. According to the invention, the composition mainly includes flower of sulphur, a plant which contains catechins and a tannin agent, as well as a pharmaceutically acceptable medium. The invention also relates to the method for manufacturing said composition. The invention can be used in the field of treating or preventing viral blood-borne diseases such as the diseases caused by the human immunodeficiency virus (HIV) or hepatitis C.

The invention discloses a high-efficiency breeding method for Lanzhou lily seedlings. The Lanzhou lily seedlings are used as explants, and the seedlings are subjected to the steps of seed collection, sterilization, germination, at least one propagation culture, strong seedling culture and bulb expansion culture. , to prepare lily seedlings. The beneficial effects of the invention are as follows: the invention uses seed germination instead of scale cuttings to produce seedlings, blocks the intergenerational spread and accumulation of viruses caused by scale cuttings, and significantly reduces the viral load of lily seedlings compared with the prior art , improve the heterogeneity of the seedling population, and effectively solve the defects of virus accumulation and narrow genetic background caused by asexual reproduction in Lanzhou lily seedling propagation. The breeding method can be used for the preservation of Lanzhou lily germplasm resources and the factory breeding of seedlings, which is beneficial to the breeding of new Lanzhou lily varieties, the rapid popularization of excellent varieties, the preservation and innovation of germplasm resources, and the improvement of the yield and quality of Lanzhou lily. .

The present invention provides methods for lowering a viral load of a virus resistant to an antiviral drug by inducing cytotoxic T lymphocytes (CTL) to recognize a predetermined mutated epitope within a viral protein of the drug-resistant virus. CTLs are induced by immunizing a host with a peptide comprising the predetermined mutation. The immunostimulating peptide may be further improved by epitope-enhancement for inducing specific CTLs. The antiviral protection against drug-resistant virus shown by compositions of the present invention and mediated by human HLA-restricted CTL has not been previously achieved.

The invention relates to the field of medicines and discloses an anti-A(H1N1) flu pharmaceutical composition and application thereof. The pharmaceutical composition comprises marine organisms and a traditional Chinese medicine composition. The efficient and safe pharmaceutical composition prepared from seven natural medicines has an anti-A(H1N1) flu effect, is good in curative effect, has no toxic or side effect and no drug dependence for human bodies, and is superior to the conventional drug preparation product; therefore, the pharmaceutical composition can be widely applied in preparation of an anti-A(H1N1) flu drug.
